Abag contains 4 blue balls, 7 yellow balls and 4 white balls. event a is defined as drawing a blue ball on the first draw and event b is defined as
drawing a white ball on the second draw. if two balls are drawn from the bag, one after the other and not replaced,
what is p(b|a) expressed in simplest form?

4/14 or 29%

Step-by-step explanation:

So p(B|A) basically means that we are finding the probability of b now that a has already happened.

In this scenario once a has happened, there are 3 blue balls, 7 yellow, and 4 white so the probability is 4/14 which is approximately 29%

the forst and 3rd

step-by-step explanation:

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
